Our buddy Mark Whinton from Carquestions, who always manages to find the obscure problems with today’s complex automobiles, wonders: why can’t the new Jeep Grand Cherokee tell if it’s battery isn’t being charged? As he points out, this omission could leave drivers stranded if their accessory belt were to break, without ever warning them of the problem. Is Mark nit-picking? Possibly, but in this business, one lesson gets learned again and again: you gotta sweat the details. In light of Mark’s research we’re as curious as he is: did Chrysler simply overlook this, or is this a case of conscious decontenting? Over to you, ChryCo…

The source of today’s Quote Of The Day, a BMW M Division engineer, is clearly not a native English speaker, but he reveals just where performance cars like the new M5 are going when he says:
More and more demand is from our test engineers from the referring(?) departments and they come over and 80%, 90% are only working on the electronic systems. The other 10, 20 percent are working at the car, under the car….
Of course, the M engineers aren’t developing a car from the ground up here, but it’s still amazing that the workload is so unevenly weighted towards electronic rather than, for lack of a better term, “greasy hands” work.
Though the next-generation of Mazda’s rotary engine has been in development since 2007, and has been the subject of several TTAC Wild-Ass Rumors, WardsAuto reports that the unique engine design could well be reaching the end of its life.
Kiyoshi Fujiwara, Mazda executive officer-product planning and powertrain development, says there is “huge discussion” within the Hiroshima, Japan-based company whether to continue on with a rotary engine.
Fujiwara says economic hardship has some top brass looking for programs to cut, and that the engine program is on the list.
Continuing development of the rotary has been halted for now, but he hopes it will resume in the future, noting the technology is a part of Mazda’s DNA.
Without identifying what exactly they are, Fujiwara says three major problems were identified with the current generation of rotary engine, but that two of the three have been overcome. Still, Mazda says that only one thing will save the rotary engine at this point: success with Mazda’s new suite of SKYACTIV technologies. If these fuel-saving measures spark new interest in the Mazda brand, says Fujiwara, then Mazda might have enough cash to invest in its rotary engine. Alternatively, a Mazda-developed Wankel engine could be used as an electric range-extender. In any case, don’t expect a new Mazda rotary before 2017… if ever. Here’s hoping Mazda is able to keep this unique, distinctive drivetrain alive for future generations of enthusiast drivers.
In my review of the VW Golf blue-e-motion on Tuesday, I noted that “the holy grail of EV development is a multi-speed transmission,” but that nobody has been able to build one that can reliably handle the 100% torque at zero RPM characteristics of an electric drivetrain. Tesla tried two different multi-speed transmissions (from X-Trac and Magna), before giving up and going with the single-speed setup that every production EV now uses. Nobody has even talked about a multi-gear EV since… until now. With Fisker’s Karma about to go to market, CEO Henrik Fisker tells Autocar that his firm is developing a multi-speed EV gearbox, and that it would improve performance in EVs like the Karma, saying
With the torque at the wheels increased by the use of a gearbox, Veyron levels of performance should be possible.
We’re as excited as anyone else by the idea of an EV with shiftable gears, but this sounds more like Fisker trying to drum up some hype for the Karma launch. After all, the Karma launches to 60 MPH in a leisurely 7.9 seconds in “stealth” (EV) mode and 5.9 seconds in “sport” mode with gas power to up the wattage… a far cry from Veyron performance. As C&D puts it:
The Karma’s initial surge is sufficiently potent to avoid damnation as a slug. But the physics conspire against it keeping pace with other $100K sports sedans.
Lugging over 4,000 lbs is certainly easier with a multi-gear transmission, but given the reliability challenge, we’d be more likely to trust an EV transmission from a reliable supplier rather than a boutique luxury PHEV maker. And until Fisker can back up the Veyron reference with some hard evidence, we’re filing this one under “intriguing but unlikely.” Still, it’s exciting to know that this technical challenge is still out there, unconquered by major manufacturer or feisty startup… in a world where cars are becoming increasingly mundane, the multi-gear EV transmission challenge is a throwback to the golden years of automotive development.
Tesla will begin supplying Toyota with components for its electric RAV4 a year earlier than previously planned, reports Bloomberg, a move that will have Toyota paying $100m for the drivetrains rather than the previously-agreed-upon $60m. According to a Tesla SEC filing, the EV specialist firm will supply Toyota with
a validated electric powertrain system, including a battery, charging system, inverter, motor, gearbox and associated software which will be integrated into an electric vehicle version of the Toyota RAV4. Additionally, Tesla will provide TMC with certain services related to the supply of the Tesla Battery and Powertrain.
There’s still no word about how many of these RAV4s is Toyota planning on selling over those two years, or where will they be assembled, but it sounds like Toyota isn’t trying to launch quite the EV offensive that some green car blogs seem to be hoping for. As one analyst puts it to Bloomberg, $100 million “isn’t a huge amount for Toyota, so this allows them, with only modest downside risk, to participate in what Tesla is doing.” That sounds about right…
It’s been 27 months since I wrote a check for $5,000 to Tesla Motors, my deposit on a Model S sedan. As owner number P717, I’ve gotten some modest bennies to keep me interested till the expected delivery date of mid-2012: a test drive in the Roadster, an invitation to the opening of the New York Tesla store, and some nice promotional swag (T-shirt, coffee mug, and, most recently, a cool little remote-control toy Roadster) .
Last week I was invited to an owners-only preview before a Model S promotional event in Greenwich, Ct. Set in the posh clothing store Richards, just across the street from an Apple store, the event featured a sinuous dark red early proof-of-concept prototype of the Model S. Unfortunately, we weren’t allowed to drive, sit in, or even touch the car (“It cost more than $2 million to build,” we were told). But the black-clad Tesla reps on hand offered some intriguing technical info about the car that, to my knowledge, had not been previously revealed. Among the more interesting tidbits:
Three times now, GM has planned to build a plug-in hybrid (PHEV) version of its Theta-platform crossovers, once with the Saturn Vue, once with the Buick “Vuick” and now, according to Reuters
General Motors Co has canceled plans to develop a plug-in hybrid vehicle based on the current Cadillac SRX crossover platform, deciding the project was not financially viable, three people with direct knowledge of the project said.
While two of the sources said the plans could still be revived on a future platform, they and two others familiar with the matter said engineers involved had been reassigned to other projects.
Back in early days of the program, the plan was to bring a Vue PHEV to market as soon as 2010, but the death of Saturn (and other difficult-to-identify issues) forced a change of plans. The Buick version was literally laughed out of consideration in what was the first-ever Twitter-based future product killing. But given that hand-picked members of the public were driving mules nearly two years ago (see video), we figured enough development had been done that GM essentially had no choice but bring the troubled Theta PHEV to market. Today’s cancellation of the SRX version is therefore just a little confusing…

Yesterday we gave GM kudos for addressing its lingering vehicle weight issues by redesigning the head of its popular 3.6 liter V6, and shedding 13 lbs in the process. It was, we noted, the kind of news that showed GM is staying focused on the nitty-gritty of product development, sweating the details. But, according to a fascinating piece by GMInsideNews, new-product development at GM still has its issues. Specifically, Cadillac’s development of a new BMW 3-Series fighter, known as ATS after its “Alpha” Platform, has faced more than its fair share of what GMI calls “drama.”
Turf battles, unnecessary “wants” on checklists and ultimately a severe case of “Mission Creep” have created a vehicle that now needs a crash diet, according to GMI’s sources both within GM and at suppliers working on the Alpha/ATS program. For a vehicle that’s taking on an institution like the BMW Dreier (not to mention costing a billion dollars to develop), these are troubling signs indeed.

Doubtless somewhat shocked and surprised about GM Chairman/CEO/Non-Car-Guy Ed Whitacre’s decision to take over product planning responsibilities, Automotive News [sub] did some digging into the decision, and offers a full report. According to AN’s GM sources, the decision comes down to one fundamental goal: holding lower-tier executives accountable for decision making. By reducing executive reviews of forthcoming vehicles by one third, or about four times per development cycle, lower-level executives and engineers will have more freedom to make decisions, and will spend more time developing and less time preparing data for executive reviews. And lest you think this decision doesn’t merit your attention, consider this: though GM’s bureaucracy had created incredibly long lead times, most automakers hold about ten executive reviews per new product. By cutting to four, GM is taking something of a step into the unknown.
The executive shake-ups show no signs of stopping at GM, as Ed Whitacre ended the week with yet another re-shuffle. And this time Whitacre himself is the big winner. Automotive News [sub] reports that Whitacre has assumed control of GM’s global product planning, leaving former planning boss Tom Stephens with the more prosaic responsibility of overseeing new product development. Whitacre will be assisted by new VP for product planning Steve Carlisle, who, unlike Whitacre, actually has some experience in product planning. Carlisle replaces Jon Lauckner, who will head up GM’s new venture capital unit. But the big news here is that a man who only just learned the term “segment” about five and a half months ago, is now in charge of GM’s global product planning. Quick learner or egomaniac?
Honda hasn’t always replaced its bread-and-butter compact, the Civic, every five years. The Mk.1 Civic soldiered from 1972 until 1979. The second through fifth generations were replaced on a regular four-year schedule, before Honda settled into a five-year product cadence with the sixth generation (1996-2000). If it were to keep with that cadence, we’d be seeing a ninth-generation Civic sometime this year, replacing the Mk.VIII, which debuted in late 2005. According to Automotive News [sub], however, Honda is holding off on releasing a new Civic until 2011. What gives?
Bob Lutz may have left GM, but TTAC’s not through with the man of Maximum just yet. One quote in particular, from an “exit interview” with gm-volt.com, exemplifies the kind of candor that seems likely to disappear from GM along with Lutz. Possibly for good reasons. Well, good PR reasons, anyway. After all, with Lutz unable to deny that GM will lose money and/or battle sticker shock with its forthcoming Volt EREV, he’s the kind of guy who will tell the unspeakable truth instead of playing coy like a good PR man. To wit:
How do we get the cost down without in any way diminishing the value of the car in the eyes of the customer? By just doing some more elegant engineering than we did the first time around where we inadvertently did some belt and suspenders stuff because we wanted to move fast. Now as we look back at the car we say ‘gee I wish we’d done his different,’ …’ gee I wish we’d done that different’ because this is a very expensive solution and we could have done that for a lot less money.
That faint sound you just heard was Ed Whitacre expelling fillet of rattlesnake out his nose after reading that little nugget. Meanwhile, you’ve heard it from the horse’s mouth: the Mk.1 Volt will be expensive, unprofitable, and unpolished. Or, to use a PR term, “belt and suspenders.”
The ongoing kerfluffle over Toyota’s recall of over 2m vehicles for a gas pedal defect which (allegedly) caused unintended acceleration has caught much of the automotive media flat-footed. How could it be, many have wondered, that the automaker most associated in the US market with the concept of quality has slipped so badly? As TTAC’s Steve Lang recently discussed, Toyota has been on a decontenting binge since the mid-to-late-1990s, putting profit above the quality obsession that had defined its operations up to that point. As a result, the current generation of decontented Toyotas and accompanying quality issues and recalls can be seen as the culmination of a long-term trend. But why did that transition take place? Though it’s easy to blame greed and mismanagement for the decline in Toyota’s quality, the decline in standards was actually a natural progression of Toyota’s constantly-evolving, efficiency-obsessed production system.
For most of the last 20 years, Ford and Mazda have enjoyed a symbiotic relationship which worked quite well. Ford needed Mazda’s engineering and Mazda needed Ford’s volume to keep their profit margins. In short, everyone was happy. Then came the recession. Ford needed money and it needed it fast, so they mortgaged their logo, cut staff and closed factories. But curiously, Ford divested a huge chunk of Mazda which netted them, in the auto world, very little money. Ford reduced their 33.4% stake in Mazda to 13.4%, netting $540 million, but effectively losing Mazda. Not that Ford’s Mark Fields is worried.
